Anatomy 101: Shins

  • by Admin
  • Feb 14, 2018

This month we are taking a look at our shins. Our shins are made up of two bones and about 20 muscles

we are going to looksome of them as we have already covered the majority of them last month. The shins act as a connecting bridge between the upper leg and the ankle foot that distributes load to the ankle and then the foot.

Let’s start up with structure of the shins
Section I: Structure
Your shins are made up of two bones:

  • Tibia
  • Fibula
The tibia has a very interesting and important architecture. The proximal (closest to the head) acts as a plateau this is why it is known as the tibial plateau. I know very original, right! This is where the thigh bone (femur) sits on, we will get into this next month and the next couple of months after that, this bone has quite a lot of “jobs” to do. You will see why. The distal aspect (furthest away from the body) cradles the medial (toward the inner part of the body) aspect of the talus.
Just lateral (towards the outside of the body) is the fibula, this bone sits just underneath the tibial plateau and acts as a supporting beam for the tibial plateau. The distal aspect (furthest from the head) cradles the lateral aspect of the talus and the calcaneal bone (we discussed this in last months blog posts extensively). The picture below gives you an indication of what I am saying.

As you can see this is not the best way to distribute forces down to the tiny bones in our feet but that is why we have close to 20 different muscles in our lower leg to not only distribute those forces but also to propel us in motion.
Section II: Muscles
Almost all of the muscles in the foot and ankle start in the shin so to over them would be extremely redundant. So, I am just going to name them, and you can go back to last months blog posts and see for yourselves what they do.
  • Anterior Tibialis
  • Peroneus Longus
  • Extensor Digitorum Longus
  • Peroneus Brevis
  • Extensor Hallicus Longus
  • Peroneus Tertius
  • Gastrocnemius
  • Soleus
  • Posterior Tibialus
What wasn’t mentioned was the deep muscles of the shins. These muscles keep the two bones together and strong. It is
  • Popliteus
  • And the fascia that holds the tibia and fibula them together
Now the popliteus muscle is usually a knee muscle that we are going to look at when we tackle the knee next month, and the fascia that holds the tibia and fibula together we can’t really strengthen (or loosen for that matter) fascia as the composition of fascia is different than muscle.

Next week we are going to look at one of the major reasons why we have a problem with running especially with runners. Hint, hint it’s not muscular related.
